ARTHUR LEVJIS COCZ-IRANE, OF TORONTO, ONTARIO, CANADA.

Patented Nov. 22, 1921.

Serial No. 494,248.

Be it l-znown that 1, Autumn Lnwis Coon- V of .i y of Toronto, in the county of .'..cc of Ontario. Carla. a sub- 12 ring of Great Britain, rare inented certain new and useful improvements in Clamps, of which the following is a speciiication.

This invention relates to devices for fastening ropes, ties, laces and the like, and my object is to o vise a clamp particularly adapted for with straps a. d webbing r-xhieh simple, neat, easily constructed and assembled, and easily quickly engaged or released.

I attain my object by means of the constructions hereinafter described and illus trated in the accompanying drawings in which Figure l is a plan view of my improved clamp;

Fig. 2 a longitudinal section of the same;

Fi 3 a plan view of a slight modifica- 4 a side elevation of the same; and

5 a longitudinal section showing the body member and clamping member in open position.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

For the sake of clearness the device is shown in the drawings on an enlarged scale.

1 is a body member preferably formed of sheet metal stamped to sha e and having a forwardly extending tongue 2, and, intermediate its ends, rearwardly facing shoulder 3 forming a bearing. d is a clamping member formed as an open quadrangular frame. vl hilc usually all four sides would be present in this frame, it it is desired one side may be omitted, as shown in Fig. 3, to facilitate the introduction between the body member and the clamping member of the strap or webbing 5 which is to be gripped. The outer end of the body member is shaped and adapted to cooperate with the outer end. of the tongue and clamp the strap or webbing, as will be understood on reference to Fig. 2. The rear member 6 of the clamping member forms a journal against which bearing the shoulder 3 lies. The rear end of the body member is provided with a slot 7, which provides means for the permanent engagement of one end of the strap or strip of webbing. The body member is held 1n (fife gement with the journal 6 by means of tongue 0'. preferably formed integral with the body member and overlying at its free end the journal 6. Vfith this ar member and clamp rangement the body assembled entirely withmember are readily out the use of tools. It is preferable that the spring shall be utilized to tend to hold the body mem and the clamping member in clamping position. This is most readily effected by forming the flat 9 on the under side of the journal engaging the underlying part of the body member. It is evident that the body member cannot be rocked on the journal without springing the tongue 8. The desired result is thus attained. A second flat 10 is also formed on the journal at its forward side, which lies flat against the underlying part of the body member when the latter is swung up in the position, shown in Fig. 5. The body member cannot then be swung down without springing the tongue. The body member and clamping member may thus be held in an open position to facilitate the introduction of the end of the strap or piece of webbing therebetween. The body member may then be swung down and will be resiliently held in the clamping position thereafter. It will be evident that other deformations of the journal or the contacting parts might be employed to serve the purpose of the flats 9 and 10, and which would fall within the scope of my invention. It is preferable to emplov a loop to hold down the free end of the strap or webbing in which the device may be em ployed. I therefore prefer to form a loop 11 integral with the clamping member et. A separate loop member 12 may, however, be employed, as shown in Fig. 4, held in place in a loop formed by doubling the end of the strap 13.

It will be noted in the form shown in Fig. a integral lugs 14 are formed at the rear end of the body member which are bent over to clamp the doubled end of the strap against the underlying part of the body member. Rivets or staples 15 will be employed to secure the parts together.

It will be seen from the construction described that the device is exceedingly simple, in one form comprising only two parts, which parts are easily assembled without the use of tools. The device is also very elfec' tive as a clamp, and is very easily operated.

lt will be understood, of course, by simple modification of the design it may be adapted for use for a great variety of forms of ties other than the flat strap shown.

What I claim as my invention is 1. A clamp comprising a body member formed with a forwardly extending tongue and a rearwardly facing shoulder intermediate its ends forming a bearing; a clamp member formed as an open quadrangular frame,the rear part of the body member overlying the rear transverse member of the frame and forming a journal against which the bearing shoulder lies and having its outer end adapted to cooperate with the outer end of the tongue to form clamping means; a spring plate on the body member engaging over the journal, the latter being shaped to engage one of the contacting parts to tend to hold the clamp member in clamping position.

2. A clamp comprising a body member formed with a forwardly extending tongue and a 'rearwardly facing shoulder interme diate its ends forming a bearing; a clamp member formed as an open quadrangular frame, the rearpart of the body member overlying the rear transverse member-of the frame and forming a journal against which the bearing shoulder lies and having its outer end adapted to cooperate with the outer end of the tongue to'form clamping means; a spring plate integral with the body member and engaging over the journal, the latter having a flat thereon engageable by the spring, whereby the spring tends to hold the clamp member in clamping position.

3. A clamp comprising a body member formed with a forwardly extending tongue and a rearwardly facing shoulder interme- V diate its ends forming a bearing; a clamp member formed as an open quadrangular frame, the rear part of the body member overlying the rear transverse member of the frame and forming a journal against which the bearing shoulder lies and having its outer end adapted to cooperate with the outer end of the tongue to form clamping means; a spring plate on the body member engaging over the journal, the latter being shaped to engage one of the contacting parts to tend to hold the clamp member in either of two positions, the clamping position or an open position.

i. A clamp comprising a body member formed with a forwardly extending tongue and a rearwardly facing shoulder intermediate its ends forming a bearing; a clamp member formed as an open quadrangular frame, the rear part of the body member overlying the rear transverse member of the frame and forming a journal against which the bearing shoulder lies and having its outer end adapted to cooperate with the outer end of the tongue to form clamping means; and means on the body member overlying the journal and serving to hold the said member inposition relative to the journal.

5. A clamp comprising a body member formed with a forwardly extending tongue and a rearwardly facing shoulder intermediate its ends forming a bearing; a clamp member formed as an open quadrangular frame, the'rear part of the body member overlying the rear transverse member of the frame and forming a journal against which the bearing shoulder lies and having its outer end adapted to cooperate with the outer end of the tongue to form clampmg means; and spring means integral with the body member overlying the journal and serving to hold the said member in position relative to the journal.

6. A clamp comprising a body member formed with a forwardly extending tongue and a rearwardly facing shoulder interme diate its ends forming a bearing; a clamp member formed as an open quadrangular frame, the rear part of the body member overlying the rear transverse member of the frame and forming a journal against which i the bearing shoulder lies and having its outer end adapted to cooperate'with the outer end of the tongue to form clamping means; means 011 the body member overlying the journal and serving to hold the said member in position relative to the journal; and a loop integral with the rear part of the frame through which a strap may be drawn.
